My 17 year old son put this together in about 90 minutes start to finish. I helped him figure out the drawer-sliders at the end, but otherwise it's not too bad to assemble. The box is very heavy to bring inside and you'll want to do this in a large open area so you can lay it all out. The pictures and instructions are pretty weak, but you can totally figure it out if you're not in a hurry. That said- the cabinet feels pretty sturdy, is generous in size and looks great in the office. I'm so happy I didn't get a particle board filing cabinet, this is much nicer. I'm planning on purchasing a second one.
